John 1:19-23 NIV

[19] Now this was John’s testimony when the Jewish leaders in Jerusalem sent priests and Levites to ask him who he was. [20] He did not fail to confess, but confessed freely, “I am not the Messiah.” [21] They asked him, “Then who are you? Are you Elijah?” He said, “I am not.” “Are you the Prophet?” He answered, “No.” [22] Finally they said, “Who are you? Give us an answer to take back to those who sent us. What do you say about yourself?” [23] John replied in the words of Isaiah the prophet, “I am the voice of one calling in the wilderness, ‘Make straight the way for the Lord.’ ”
